When scaling in Windows is set to a non-integer level (such as 125% or 150%) text cursors in all fields appear with inconsistent widths. The attached picture is of a standard QLineEdit with no styling set, and the minimal code needed to produce this is simply showing any widget with an input field.

I'm using PySide for this (tested in 6.1.2 and 6.1.3) but the same issue happens when using PyQt6, so it doesn't seem to be a PySide specific bug.
